RotateY()

Matrix33 & SRL::Math::Types::Matrix33::RotateY ( const Angle & angleY )

inlineconstexprinherited

Apply Y-axis rotation to the current matrix.

Modifies the current matrix by applying a rotation around the Y-axis. This is equivalent to multiplying the current matrix by a rotation matrix.

The Y-axis rotation matrix is: | cos(θ) 0 sin(θ) | | 0 1 0 | | -sin(θ) 0 cos(θ) |

Parameters

angleY

Rotation angle around Y-axis.

Returns

Reference to this matrix after rotation.

Note

This is ideal for continuous transformations like animation as it modifies the existing matrix rather than creating a new one.

Matrix33 transform = Matrix33::Identity();
transform.RotateY(Angle::FromDegrees(45)); // Rotate 45° around Y
